TO ALL PERSONS TO WIIOM THESE PRESENTS SHALL COME:

Be it known that I, CALVIN D. SMITH, of Baldwiuville, in the county of Worcester, and State-of Massachusetts, haveinvented a new and useful Improvement in Journals of Axles or Shafts; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a vertical section of a wheelaxle journal and its box or bearing as provided with my invention'.

Figure 2 is a side elevation, und' Figure 3 an under side view of the journal.

In such drawings, A denotes the journal, and B the box or bearing.

Incarrying out my invention, I rst form on the journal, at or near its middle, a. groove, a, to extend transversely around the journal, and t o open into another groove, b, iuade longitudinally in the bottom of the journal. From the outer e'nd of the journal I here a hole or passage, c, inclining downward to the junction of the two grooves a b, or into the latter groove; and form in and at the outer end of the passage e a female screw, to receive a screw-plug, d. Y

The journal may have a shoulder, e, to abut against one end of the box; and it may also have a screw, f, cut upon it, near itslend, to receive a nut, g, to keep it in the box, or the latter on the journal.

In order to supply the box and journal with oil at -any time` it may be poured from a feeder`into the upper end of the passage c, when open. vIt will run through this passage int'o the grooves a and b, and will rise inthe groove a, and in the passugee, to a level with the lower part of the mouth of the said'passage. Thus the passage e and the grooves a and Il consntitute areservor to hold oil, and the groove serves to distribute the oil over the entire inner surface of the'bolv while it may he in revolution. Y

' I. claim the arrangement of the inclined passage c, and the grooves a and b, together and with thejournal, as specified.

' CALVIN D. SMITH.
